Which of the following function types exhibit the end behavior (PICTURE INCLUDED)

Nostrana [21]

Answer:

$y=x^n$ ; $n$ is even and greater than zero.

The absolute value function $y=|x|$

Step-by-step explanation:

The power function;

$y=x^n$ ; $n$ is even and greater than zero, is symmetric with respect to the positive y-axis.

As $x\rightarrow \infty,f(x)\rightarrow \infty$ and as $x\rightarrow -\infty,f(x)\rightarrow \infty$

The absolute value function $y=|x|$ also has the same end behavior.

The remaining functions in the options provided do not exhibit this end behavior.

Classify the following is rational or irrational(a) √45

marshall27 [118]

The numbers that can be expressed in the form of a fraction are called rational numbers. While that numbers that cannot be expressed in the form of a fraction are called irrational numbers.

$\sqrt{45} =\sqrt{3 \times 3 \times 5}$

$\sqrt{45} =3\sqrt{5}$

$3\sqrt{5}$ is an irrational number, it cannot be expressed in the form of a fraction.

When constructing an angle bisector, why must the arcs intersect?

Black_prince [1.1K]

<span>The arcs must intersect because the point at which the arcs intersect forms the halfway point of the angle; if they don’t intersect, the angle will not be bisected. </span>
